IVF + ET complications
The most common complication is the ovarian hyperstimulation syndrome (OHSS).
Its severe form occurs in 3-5 % of cases. Each patient suffers from a certain degree of ovarian hyperstimulation after treatment when she feels a full and bloated abdomen, but this eventually fades away. A certain group of patients responds to hormonal stimulation with exaggerated response and develops the OHSS. If you have nausea, decreased urination and significant abdominal tension, it is a severe form of OHSS. Women with polycystic ovary syndrome (PCOS) and young women are primarily at risk of developing the OHSS.
It is necessary to say that the OHSS is discomfort for the patient; for the transferred embryo(s), however, it is an ideal state and patients with OHSS get "pregnat" well. However, if pregnancy occurs after ET, the condition may temporarily worsen. To prevent this, we cannot do the embryo transfer (ET) in severe OHSS forms and we rather freeze all the embryos.
Other complications, such as inflammation or bleeding after egg retrieval (OPU), are rare.
